Ikea Malm dresser white - gray drawers?

Hello everyone,
I hope you can help me and that I won’t be immediately stoned because I didn’t introduce myself.

I have a question about the Malm dresser in white and the tabletop Linnmon and the Lerberg trestle legs.

We bought the Malm dresser in white with 3 drawers and, when unpacking it at home, saw that the rails for the drawers, as well as the bottoms, sides, and backs of the drawers, are gray (or rather mud-colored).
The fronts are normally white. Is this normal or was the box assembled incorrectly?

Another question would be about the Linnmon tabletop and the Lerberg trestle legs. The tabletop already has pre-drilled holes. Is there any kind of fastening for the trestle legs? There was nothing else included in the package.

A call to the Ikea hotline unfortunately didn’t help much... :(

Thank you very much and best regards!

Yes.

Is there any attachment for the trestle tables?

Not that I know of. The tabletop is simply placed on the trestles, so it is best if the tabletop is against a wall on one side. The holes are for attaching individual legs. If you want to screw the tabletop onto the trestles, you have to drill holes into the trestles yourself. Since the tabletop is hollow, the existing holes should be used.
